If using drawbitblt() or drawimage() to draw a bitmap that is larger than the screen size, then how would you scroll around the image, especially the parts of the image that are off screen? Preferably without redrawing the image, but simply by moving its position if possible.

Is there any information about the flags that are available with these two options above? The brief documentation that accompanies the function descriptions is little more than a name for each flag rather than an explanation.

You can't do that properly. if you're using pocketC V3; and you don't need the menu or other parts of the screen. you can resize the main window to the size of the bitmap with wndmove(1,0,0,bitmapWidth,bitmapHeight) then draw it at 0,0 and move the whole window ( to a negative position i.e. wndmove(1,-6,-20,bitmapWidth,bitmapHeight). It may work but i have never moved it to a negative position (positive works).

For the flags, i think keywords (OR, XOR, AND etc...) are enough. it just plots the color of the point in the bitmap OPERATOR the color of the point on the screen.

i.e.
point in the bitmap: 255, 255, 255
XOR
point on the screen: 255, 255, 255
= 0, 0, 0

like this, you move the console window, which is not the main window. to move the main window, you must use the V3 device compiler. i don't know if it works on the desktop compiler. then the id is really 1. you can draw the bitmap on the main window and move it.
But it's not worth because Kevin (not you but Kevin Cao) hasn't added the points that are out of the screen coordinates in the paint routine of the main window. or doesen't get the new window size. so, the points that are out of the screen when you draw the bitmaps are not redrawed when the window is moved. So, this is white. You can redraw the bitmap each time you move the window (but i think it's not what you want) But it will be erased each time a control com on it:
i.e. if you open the start menu or the input pannel, they will leave a white rect behind them when they are closed.

I hope you will understand me, it's not easy to explain.
just remember that my idea can't work.

I to would love to know how to use the x controls and dil if you could maby add an example to the web page or in the help file it would be great thanks <img src=icon_smile_big.gif border=0 align=middle>

It's just that You don't see the edit screen unless you are posting a message, and when I'm posting a message I don't tend to look at what edit features that are available, but get on with the message and get out of it.
